只要30分鐘跟一條棉線

產品描述 (Description)

中文版本

這是一個展示伯努利定律的趣味科學玩具！只需輕輕一吹，原本垂下的線圈就會在氣流中神奇地盤旋懸浮，看起來就像在跳舞一樣。

• 教學意義： 適合給孩子演示流體力學中「流速快、壓力小」的物理現象。
• 列印簡單： 無需支撐，一體成型（或簡單組裝）。
• 材料需求： 除了列印件，你只需要一段細棉線（建議長度 40-60cm）並將其兩端打結成環。

操作技巧： 將線圈掛在噴嘴處，持續且穩定地吹氣，線圈就會自動展開並持續旋浮！

English Version

Experience the magic of Bernoulli's Principle with this simple yet addictive 3D-printed toy! By blowing air through the tube, the string loop will magically expand and levitate in the airflow.

• Educational & Fun: A perfect STEM toy to demonstrate fluid dynamics to kids.
• Easy to Print: No supports required. Quick print time.
• Extra Material Needed: You only need a thin piece of string (approx. 40-60cm) tied into a loop.

How to Play: Hang the string loop over the nozzle and blow steadily. Watch as the string defies gravity and "dances" in the air!
